I have null in a row if there no number. I need to put empty string in a row instead of null.
<td>${number}</td>. // null, if there no number,
so, Am I thinking in the right way? :
!number ? number : ""
This will check if the variable's type is number and if not it won't render anything:
typeof number === 'number' ? number : ''
try
`<td>${!number ? '' : number}</td>`
if there is no number then display '' else display number
You can use Nullish coalescing operator (??) that returns its right-hand side operand when its left-hand side operand is null or undefined, and otherwise returns its left-hand side operand.
Working Demo :
let number = null;
document.getElementById('numberText').innerHTML = number ?? ''<p id="numberText"></p>
